The NHGRI Data Access Committee (DAC) currently manages 16319 data access requests (DARs) for access to 5095 projects in dbGaP.
Between 2019-11-24 and 2020-12-24 NHGRI reviewed 7009 DARs. Of these, 5712 were accepted, 631 were downloaded, 2337 had a previous version downloaded, and 1023 were rejected. The average amount of time from when the Principle Investigator (PI) submited a DAR to the final decision by the DAC was 9.3 days. The average time to an accepted decision was 9.4 days, while the average time to a rejected decision was 9.3 days. Figure @ref(fig:compline) is a barplot comparing the NHGRI DAC to time to final decision to the average across all NIH DACs during the same time interval.

Between 2019-11-24 and 2020-12-24, 1705 PIs have submitted DAR to studies released by NHGRI. Among these PIs, 1315 have also submitted DAR to studies released by other DACs. PIs who submitted DARs to NHGRI also submits, on average, 18.93 DARs to all DACs for 2.11 projects.
During this reporting period, 21 new studies were released by NHGRI through dbGaP. A total of 719 DARs were made for these newly released studies. Study phs000452.v3.p1 (Melanoma Genome Sequencing Project) was the most requested dataset from the NHGRI DAC with 296 requests. The following word-cloud provides a graphical summary of the combined research use statements (RUS) from all DARs requesting this study. The larger the word appears in the wordcloud, the more frequent the word in the set of RUS.
